Boodles

Not in anyway shape or form would this shop be an every month visit, let alone everyday (unfortunately) but on the occasions I have been in the Boodles store on King Street, the service has been absolutely wonderful. They have gorgeous collections of rings and necklaces, and are famous for their engagement jewelry. Not cheap, but you have to pay for design and quality.
You can buy online, unlike many sites for high-​end shops, but if splashing out squillions for a rock won’t impress your bank manager, you can also transfer your dream diamond to an online wish list. Get help with your treasure hunt using the Find Something Special search facility, but if you spot the ideal engagement ring hold your horses and download the useful Look Before You Leap booklet. The Highlights section includes celebrities adorned with Boodles wares — although the picture of Victoria Beckham is ancient.
